This week is the first after the Octave of Easter in the 1962 Benedictine Office, so the season of Eastertide.
Eastertide has its own Ordinary texts, including hymns for Matins, Lauds and Vespers, which can be found at MB 615/MD 346*/AM 466 ff.
During Eastertide the invitatory antiphons, antiphons, responsory verse and versicles (at the end of each Nocturn in Matins; associated with the chapters at Prime to None and Compline; and with the canticles at Lauds and Vespers) have the word alleluia added to them if one is not already included in the text.
Note that at Matins, each Nocturn has only one antiphon, and the single short reading is the same each day; at Lauds Psalm 50 and the two variable psalms of the day are said under one antiphon; and at Vespers the psalms are all said under one antiphon. At Sunday Lauds, Psalms 92 and 99 are said instead of Psalm 50&117. At Lauds and Vespers there are canticle antiphons for each day of the Eastertide week.
