Binary encounter peaks for 0 deg electrons in collisions of 0.8 MeV/amu Bi(q+) with H2 and He

Abstract

The binary encounter electrons produced in 0.8 MeV/amu Bi(q+) on H2 and He collisions were measured at 0 deg with respect to the beam direction. The incident projectile charge (q(sub i)) dependence of intensity of the binary encounter electrons in the region of q(sub i)/Z(sub 1) less than 0.4, Z(sub 1) being the projectile atomic number, was measured. In the case of a heavy projectile and in this q(sub i) region, the intensity of the binary encounter electrons increases as q(sub i) increases. The peak energy shift of the binary encounter electrons is explained by the Bohr-Lindhard model.

0.8MeV/amuのBi(q+)とH2およびHeとの衝突で生成された2体衝突電子をビーム方向に対して0度で測定した。qi/Z1＜0.4(Z1は入射粒子原子番号)の領域における2体衝突電子強度の入射粒子電荷(qi)依存性を測定した。重い入射粒子かつこのqi領域の場合、2体衝突電子の強度は、qiが増大するにつれて、増大する。2体衝突電子のピークエネルギーシフトはBohr-Lindhardモデルによって説明できる。
