Contents of a substantial folder so inscribed. The material is very diverse, and not all in Frisch's hand; it includes notes on the literature, drafts for papers or reports, drawings of apparatus, calculations and results, ideas for experiments and techniques, etc.
Notes and sequences clipped together by Frisch have been preserved as such.
B.52: Dated sequences of notes, 1932-1937.
Includes:
'Ablenkung von Mol. Str. in mag. Feld'. 3 pp. sequence, kept with other notes on magnetron, B-recoil, etc., some dated October 1932 (during Frisch's period in Stern's laboratory at Hamburg).
Notes and draft for short talk on work of Stern's laboratory (on proton, and on diffraction anomalies). In English, possibly for talk at Birkbeck, or at Copenhagen. c.1933-34.
Sequence of notes, various dates September-October 1936, on 'Schrägheits-korrektur', neutrons, etc.

All these items are in Frisch's original folder, which also bears notes and diagrams on the front cover.
