The application of wavelength coincidence statistics to line identification: HR 465 and HR 7575.

A Monte Carlo technique for the experimental determination of probabilities has been used to supplement standard line-identification procedures in the Ap stars HR 465 and HR 7575. The resulting identifications are divided into three categories ranging from definite to possible identifications. The identification of U ii and Pt ii in HR 465, the possible identification of Te ii, Os ii, and Pm ii in HR 465, and the possible identification of Se ii and Cs ii in HR 7575 are discussed in more detail. It is suggested that HR 465 has some of the properties usually associated with both the Hg-Mn and the Cr-Eu stars.
