摘要: The anisotropic potential developed in our previous research and the close-coupling method are applied to the HBr--$^{3}$He ($^{4}$He, $^{5}$He, $^{6}$He, $^{7}$He) system, and the partial cross sections (PCSs) at the incident energy of 60\,meV are calculated. Based on the calculations, the influences of the isotope helium atom on PCSs are discussed in detail. The results show that the excitation PCSs converge faster than the elastic PCSs for the collision energy and the systems considered here. Also the excitation PCSs converge more rapidly for the high-excited states. The tail effect is present only in elastic scattering and low-excited states but not in high-excited states. With the increase of reduced mass of the collision system, the converging speed of the elastic and excitation PCSs slows down, and the tail effect goes up.
