Precise measurements of deuteron vector and tensor analyzing powers ${A}_{y}^{d},$ ${A}_{\mathrm{xx}},$ ${A}_{\mathrm{yy}},$ ${A}_{\mathrm{xz}}$ in $d\ensuremath{-}p$ elastic scattering were performed via ${}^{1}\mathrm{H}(\stackrel{\ensuremath{\rightarrow}}{d},d)p$ ${}^{1}\mathrm{H}(\stackrel{\ensuremath{\rightarrow}}{d},p)d$ reactions at three incoming energies ${E}_{d}^{\mathrm{lab}}=140,$ 200, $270 \mathrm{MeV}.$ A wide range center-of-mass angles from...
The cross section, the deuteron vector A(d)(y) and tensor analyzing powers A(ij), polarization transfer coefficients K(y('))(ij), induced P(y(')) were measured for dp elastic scattering at 270 MeV. section are well reproduced by Faddeev calculations with modern data-equivalent nucleon-nucleon forces plus Tucson-Melbourne three-nucleon force. In contrast, or not described such calculations. These facts indicate deficiencies in spin dependence of force call extended models.
The possibility of observing neutrinoless double $\ensuremath{\beta}$ decay offers the opportunity determining effective neutrino mass if nuclear matrix element were known. Theoretical calculations are uncertain, and occupation valence orbits by nucleons active in is likely to be important. proton ground states $^{76}\mathrm{Ge}$, a candidate for such decay, $^{76}\mathrm{Se}$, corresponding daughter nucleus, determined precisely measuring cross sections proton-removing transfer reactions....
The double-differential cross sections for the Ca48(p,n) and Ti48(n,p) reactions were measured at 300 MeV.

Double differential cross sections between 0°–12° were measured for the 90Zr(n, p) reaction at 293 MeV over a wide excitation energy range of 0–70 MeV. A multipole decomposition technique was applied to present data as well previously obtained 90Zr(p, n) extract Gamow–Teller (GT) component from continuum.

Three precise measurements for elastic $pd$ scattering at $135\text{ }\text{ }\mathrm{MeV}/A$ have been performed with the three different experimental setups. The cross sections are described well by theoretical predictions based on modern nucleon-nucleon forces combined three-nucleon forces. Relativistic Faddeev calculations show that relativistic effects restricted to backward angles. This result supports two recently reported RIKEN and contradicts KVI data.
