摘要：

We study the collisions of doubly spin-polarized 85Rb atoms at millikelvin temperatures using photoassociation spectroscopy. Because the atoms are spin polarized, only triplet collisional states are formed. This leads to photoassociation spectra of a particularly simple form, which provide a very direct probe of the ground state collision. These spectra are analyzed to yield the ground state triplet scattering length -1000a0<aT<-60a0 for 85Rb, +85a0<aT<+140a0 for 87Rb, and the product of the D-line dipole matrix elements d(P1/2)d(P3/2)=8.75±0.25 a.u. © 1995 The American Physical Society.
