Determination of the Gamow–Teller quenching factor from charge exchange reactions on 90Zr

Abstract Double differential cross sections between 0°–12° were measured for the 90 Zr(n, p) reaction at 293 MeV over a wide excitation energy range of 0–70 MeV. A multipole decomposition technique was applied to the present data as well as the previously obtained 90 Zr(p, n) data to extract the Gamow–Teller (GT) component from the continuum. The GT quenching factor Q was derived by using the obtained total GT strengths. The result is Q = 0.88 ± 0.06 , not including an overall normalization uncertainty in the GT unit cross section of 16%.

Range control system

A range control system includes an input section for inputting a singing voice, a fundamental frequency extracting section for extracting a fundamental frequency of the inputted voice, and a pitch control section for performing a pitch control of the inputted voice so as to match the extracted fundamental frequency with a given frequency. The system further includes a formant extracting section for extracting a formant of the inputted voice, and a formant filter section for performing a filter operation relative to the pitch-controlled voice so that the pitch-controlled voice has a characteristic of the extracted formant. The system further includes an input loudness detecting section for detecting a first loudness of the inputted voice, and a loudness control section for controlling a second loudness of the voice subjected to the filter operation to match with the first loudness. The system further includes a music information storing section storing musical information of songs to be sung, and an automatic reproducing section for reading musical information of a selected song and outputting melody information, accompaniment information and various acoustic effect information of the selected song included in the musical information.

Analyzing powers Ayy , Axx , Axz and Ay in the dd → 3Hen reaction at 270 MeV

The data on the tensor Ayy, Axx, Axz and vector Ay analyzing powers in the dd → Hen obtained at Td = 270 MeV in the angular range 0 ◦ – 110◦ in the c.m. are presented. The observed negative sign of the tensor analyzing powers Ayy, Axx and Axz at small angles clearly demonstrate the sensitivity to the ratio of the D and S wave component of the He wave function. However, the one-nucleon exchange calculations by using the standard He wave functions have failed to reproduce the strong variation of the tensor analyzing powers as a function of the angle in the c.m.

Measurement of the tensor analyzing power T20 in the dd→He3n and dd→H3p at intermediate energies and at zero degree

The data on the tensor analyzing power T20 in the dd->^3Hen and dd->^3Hp reactions at 140, 200 and 270 MeV of the deuteron kinetic energy and at zero degree obtained at RIKEN Accelerator Research Facility are presented. The observed positive sign of T20 clearly demonstrates the sensitivity to the D/S wave ratios in the ^3He and ^3H in the energy domain of the measurements. The T20 data for the ^3He-n and ^3H-p channels are in agreement within experimental accuracy.
